An overall well-rounded teacher. Knows how to balance teaching time with work periods. Is also helpful in any way possible-tests are fair. Even if you're not good in science, you'll enjoy the class!
It's rare that you find a great teacher like this who is also good looking. He explains everything fully and is such a nice guy. You will be glad you had him. He seems mean at first, but then changes.
